Heroes VII

Well, generally, astral magic is really necessary on large GSC maps. In theory, you can break through any guard with dark magic (necromancer or with artifacts that ignore magic immunity), but as a rule, maps of this size are not played to clear the entire map, but after a certain time, players simply teleport through portals to meet the opponent.

Yes, I didn't read the whole thread, and I haven't played Heroes for a long time, but I just had to jump in and express my very important opinion.
